Mario Golf World Tour (3DS, BCSTM)

[JJ314]

I wanted to rip Mario Golf World Tour voices, but these bcstms are weird. I tried playing them in foobar2000 with the vgmstream plugin the first time and they didn't work, so I went into a hex and found out they were compressed. I thought it was as simple as removing the first four bytes, but when I put them in foobar2000 again, they played but they sounded distorted. Example: semr_goo00.dspadpcm.bcstm (converted to wav, warning: loud) - https://drive.google.com/file/d/1_QK2bmK...sp=sharing
I don't know what else to do. I have provided some non-edited samples below.
